otel_flutter_bloc 0.3.0

Flutter overlay for `otel_bloc`. Re-exports the core observer + semantics and pulls in `flutter_bloc` so Flutter apps add one dependency to get OTel coverage of every Bloc / Cubit.

All notable changes to this project will be documented in this file.

0.3.0 - 2026-10-11

Changed

• Requires dartastic_opentelemetry_api >=1.0.0-rc.4 <1.0.0-rc.5.
• Requires otel_bloc ^0.3.0, the API-only release.
• Breaking: depends on dartastic_opentelemetry_api only, no longer on the SDK. The application chooses and initializes the OpenTelemetry SDK. Parameters and fields typed with SDK classes now use the API types (APITracer, APISpan, APILogger, ...); SDK instances are still accepted wherever an API type is expected.

0.2.0 - 2026-08-10

Changed

• Dependency floors raised to dartastic_opentelemetry ^1.1.0-beta.12 and dartastic_opentelemetry_api ^1.0.0-rc.1, matching the core.
• Core constraint widened to otel_bloc >=0.1.0-beta.1 <0.3.0: the previous caret (^0.1.0-beta.1) excluded the core's 0.2.0 line, so this overlay could never resolve the modernized-semconv core it is developed against. The re-exported OTelBlocObserver + BlocSemantics surface is source-compatible across the range.
• repository URL corrected to the canonical Dartastic org casing so pub.dev repository verification succeeds.
• Docs: initialization snippets corrected to the SDK's OTel.initialize entry point (and now show the flutter_bloc import the snippet uses); links to the core package point at pub.dev instead of repository-relative paths.

Added

• Runnable example/main.dart: a counter-Cubit Flutter app with the observer installed once at startup; every state change lands as a bloc.* span.

0.1.0-beta.1 - 2026-05-16

Added

• Slim Flutter overlay for dartastic_bloc_otel. Re-exports the core observer + semantics and pulls in flutter_bloc so Flutter apps add one dependency instead of managing bloc + flutter_bloc + dartastic_bloc_otel separately.
• Targets flutter_bloc: ^9.0.0. No new types yet — the bloc observer install pattern is global (Bloc.observer = ...), not widget-scoped, so there's no OTelBlocApp-style widget to add. The package exists for the dependency-mapping convenience and to match the dartastic_flutter_riverpod_otel core/overlay pattern.

Note

This is a new package created when dartastic_flutter_bloc_otel (the package previously published under this name) was renamed to dartastic_bloc_otel. The previous package was the pure-Dart core that only depended on bloc; the name was misleading. Flutter apps that were depending on the old dartastic_flutter_bloc_otel can keep using it — the surface is now provided by this overlay, which re-exports the core and adds flutter_bloc as a dependency.
